Isn't there something about the 1958 flywheel that is different that the 56-57s also...Something about the flywheel diameter being slightly smaller? The rewind pulley might be unique as well. I can't confirm this, but remember this past discussion....
I believe you're right. The small flywheel, I think, came about when they went to the smaller gear case. Trying to put the 10 on a diet, so to speak. The recoil housings were the same, but the rope plate was different. The nylon starter pawl pivot was closer to the center on the 1958 & up versions.
Differences between the '56-'57 and '58 and up 10 HP. For the recoils the connecting links and posts were moved in for '58 and up 10 HP. On the flywheels there is a different dia. up top for the pawl engagement. Under the flywheels the same diameter for coil heels.

'55 was a different pawl setup so they won't interchange.
